We get many questions about the quality and price point of various ozone generators. \u00a0These are fair questions as there are many price points for an ozone generator with the same basic g\/hr or mg\/hr ratings. \u00a0Here we will try to lay out the biggest differences in ozone generators.<\/span><\/p>\n

The purposes of this article we will be looking only at corona discharge ozone generators <\/a>producing ozone from dry air or oxygen. \u00a0We will not be evaluating\u00a0UV ozone generators <\/a>or ambient air ozone generators used for air treatment as these both have very limited\u00a0application.<\/span><\/p>\n

Corona Cell Materials<\/span><\/h2>\n

The heart of any ozone generator is the corona cell. \u00a0This is where the corona\u00a0discharge occurs and produces the ozone. \u00a0Materials such as aluminum, tin (tin foil), low-grade stainless steel and plastics can be used to lower cost. \u00a0This is typically the case for Chinese made ozone generators. \u00a0These materials will be attached by the oxidation of ozone over time, and create leaks or a failed corona cell.<\/span><\/p>\n

As these low-quality materials degrade<\/a> they will contaminate the\u00a0oxygen\/ozone stream and\u00a0allow\u00a0impurities into the\u00a0ozone\u00a0stream. \u00a0Keep\u00a0this in mind\u00a0for water treatment or medical ozone\u00a0applications.<\/span><\/p>\n

higher quality ozone generators will use high-grade stainless steel (316L), quartz glass, ceramic, and pure Teflon. \u00a0These ozone resistant materials<\/a> will withstand ozone and create a longer life to the ozone generator.<\/span><\/p>\n

In 6-months of operation or very light use, there is no difference in corona cell materials. \u00a0Long term, after 6-months, or heavy use reliability of the ozone generator will be greatly affected. Costs will be higher to manufacture corona cells from higher quality materials. \u00a0However, the benefits are worth the cost.<\/span><\/p>\n

Transformer<\/span><\/h2>\n

To produce ozone a high voltage spark is required. \u00a0This spark is occurring at all times and is an end-point ground. \u00a0A high voltage transformer is used to create these high voltages and sparks. \u00a0This transformer must be reliable and capable of handling the torment of shorting through a dielectric to ground at a high frequency for hours at a time. \u00a0We have found the best success with open coil resonant\u00a0transformers, or oil cooled transformers. \u00a0Simple end-point transformers are less expensive and are commonly used in lower cost ozone generators, however, these will fail sooner.<\/span><\/p>\n

Electronic Driver Boards<\/span><\/h2>\n

To produce ozone a high-frequency spark is used. \u00a0Electronic components must be used to create this high frequency. \u00a0Most commonly basic Mosfet\u00a0transistors are used to switch DC voltage to create the high frequency. \u00a0Lower cost ozone generators will use one transistor to create the high frequency. \u00a0HIgher-end ozone generators will implement a series of transistors to split the workload. \u00a0<\/span><\/p>\n

Circuit protection<\/span><\/h2>\n

In the event, the corona cell is contaminated, or adverse conditions exist the ozone generator driver board should turn OFF ozone production so that the transformer does not short directly to ground and fail. \u00a0Many lower cost ozone generators do not implement this circuit protection. \u00a0Those that do, may not react quick enough to protect the electronic equipment. \u00a0<\/span><\/p>\n

Cooling fans<\/span><\/h2>\n

Ozone generators create heat. \u00a0That is a non-negotiable fact. \u00a0Many low-end ozone generators use small cooling fans that do not move sufficient air, and some use no cooling fan at all.\u00a0<\/span><\/p>\n

Ozone Concentration<\/span><\/h2>\n

Ozone generators are normally rated with mg\/hr or g\/hr. \u00a0How efficiently this ozone is produced is a measurement of the ozone concentration, normally measured in % by weight, g\/m3 or gamma. \u00a0It is important that the ozone generator you purchase produces the most g\/hr at the highest possible ozone concentration. \u00a0Higher concentration ozone will consume less oxygen, dissolve into water more efficiently,<\/a> and simply work better for every possible application.<\/span><\/p>\n

 <\/p>\n

These are a few of the most important components to review on an ozone generator. \u00a0Of course, low-quality ozone generators serve a purpose, they meet a low price point, and allow a user to determine if ozone is right for them. \u00a0However, do not be confused, a $100 ozone generator is not a lifetime investment. \u00a0And as with everything, higher quality is going to cost more.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
